How can I get all the markdown field to GraphQL node field?

Summary

I use @gridsome/source-filesystem and @gridsome/transformer-remark to grab field data to GraphQL for use. Is it possible if I can get custom field from markdown file to GraphQL?

Basic example

I have a custom named desc field in my .md file.

// a blog post md file
---
title: this is a blog
desc: this is descripton
---

This is a blog post

How can i config to fetch it successfully from query?

<page-query>
  query Posts ($page: Int) {
    allPost (page: $page) {
      edges {
        node {
          title
          desc
        }
      }
    }
  }
</page-query>

Include a basic example or links here.

Motivation

Why are we doing this? What use cases does it support? What is the expected outcome?

Because we may use custom field to define additional categories.

@freshyill I reverted to 0.2.1 for the time being and this worked to allow for custom fields. Hope that helps!
